$ProcOpn

Open procedure for $ProcDat, $ProcGet, $ProcLoc

Most Sirius $functions have been deprecated in favor of Object Oriented methods. There is no OO equivalent for the $ProcOpn function.

The $ProcOpn function is used to "open" a procedure as input to a User Language procedure via $ProcGet, $ProcDat and $ProcLoc.

$ProcOpn accepts three arguments and returns a numeric code. As of Sirius Mods Version 6.8, it is a callable $function.

The first argument is required and identifies the User Language procedure to be opened.

The second argument is an optional file name. If the second argument is not provided, or is a null string, the current file is used.

The third argument is a string that is used by $ProcGet for dummy string substitution just as if this argument had been placed on an INCLUDE statement. Note that $ProcDat does no dummy string substitution.

For example, suppose procedure TIS_PITY in procedure file HOHO contains the line

FIND1: IN ?? FIND ALL RECORDS FOR WHICH

the sequence

%RESULT = $ProcOpn('TIS_PITY', 'HOHO', - ' THESE ARE ARGUMENTS') %LINE = $ProcGet

would result in %LINE being set to

FIND1: IN THESE FIND ALL RECORDS FOR WHICH

Syntax

<section begin="syntax" /> %RESULT = $ProcOpn(proc_name, file_name, inc_string) <section end="syntax" />

$ProcOpn Function

%RESULT is set to indicate the success of the function.

-1 - Current include level not opened by $ProcOpn 0 - Procedure opened without errors 1 - Procedure is locked for edit or delete 2 - Procedure does not exist or the current user does not have access privilege 3 - Specified procedure name is invalid (null) 4 - File name invalid, or no current file, or caller does not have sufficient privilege to display/include procedures 5 - The maximum number of open procedures (5) has already been reached 6 - Insufficient space in ITBL to hold third argument; increase the size of ITBL

$ProcOpn return codes

After $ProcOpn has successfully opened a procedure, $ProcGet and $ProcDat may be used to retrieve the procedure source lines and $ProcLoc may be used to scan them.
